WebSymmetrical distribution is a statistical term that refers to a distribution of data that is mirror-image across a central value. The most common type of symmetrical distribution is the normal distribution, which is often represented by a bell curve. In a normal distribution, the mean, median, and mode are all equal. WebFeb 9, 2024 · The normal distribution is a continuous probability distribution that is symmetrical on both sides of the mean, so the right side of the center is a mirror image of the left side.
